Discussion Similar to both Gray and Hammond's. Behavior, bill size and color, and relative wing length are useful pointers: less active than Hammond's, but flicks tail and wings (like that species, but unlike Gray, which pumps tail); bill length is intermediate between Gray and Hammond's, with an orange-pink base to dark-tipped lower mandible; primaries do not extend beyond rump when perched. Sexes are similar.
